Application filed March '30, 1918. Serial No. 225,692.

To all whom it may concern:

Be it known that 1, WILLIAM MnLLon, a citizen of the United States, residing at Sebring, in the county of Mahoning and State of Ohio, have invented a new and use ful Porcelain-Kiln, of which the following is a specification.

y invention relates to porcelain kilns and more particularly to those designed for firing porcelain ware and the like during the decorating process of the same, the purpose being to construct a kiln ofthis typethat will distribute the heat generated in the fire polxes evenly throughout all parts of the 1 n.,

Another object is to construct a kiln in which a perfectly even heat canbe maintained during the time of firing the ware, thus enabling the user to produce a more perfectly finished article of ware. 1

Another object is to arrange the flue passages in such a way that all of the heat generated will come in close contact with the inner compartment walls, thereby materially reducing the amount of fuel necessary to generate a given heat. I 7

Another object is to reduce the amount of labor necessary in keeping the fire under my,

kiln owing to sary.

the less amount of fuel" necesstruction of this class of kilns, and thereby reduce the'cost of installing'the same.

With these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of construction may be tiles forming to leave passages 6 extending of the kiln and cross passages Trunriingl Partition walls:

' I The heating chamber or interior of ny. 1

kiln is constructed with fire clay or tile walls .and floor and is indicated at 1;. the usual.

2 gives access to this. heating chamber. Spaced from the walls ofthe heating ChflHI-r 1 is the brick outer shell lzand beneath door ber

the floor of this chamber are rows of the clay pillars 5, which, are arranged transversely therebetween.

6 5 longitudinally a 7 8 extending from the outer shell 4' tothe Walls of the heating chamber 1 divide the space between the said walls into a series of; Q passages or flues 9 :WlllCh are arranged tOJl communicate with the lateral passages 7 A series of fire boxes side of the kiln and beneath the level of the 10 are locatedat one floor of the heating chamber 1, as clearly each of the fire boxes 10 being in direct communication with one or i I more of the cross flues.7. A stack 11-1s arranged at the center of the top of thefkiln and is divided by a partition 12 1 extending upwardly from the top of the heating fcham-- l ber.

The partition 12 extends the I, entire .1

width of the stack, the result being that a-l separate draft is drawn upwardly upon each side of the heating chamber through the flues 9. This peculiar arrangementof the I. flues will cause the flame traveling fromthe fire boxes to spread over approximately the entire surface of the bottom-ofthefkilnla In kilns of ordinary construction theflues at '1. s v

either side, such as the flues -9 in ;m ki1n;

are joined at the top and enter the stack as is that the draft will be strongest on the side next the fire boxes or in the event the fire boxes are located directly beneath the kiln the flues on one side will always tend to draw the heaviest flame, thus heating the kiln unevenly and requiring the burning of additional fuel to raise the temperature of the underheating side of the kiln to the proper point. 7

In my construction the partition at the top of the kiln at the point where the flues enter the stack creates a separate draft for each side of the kiln and by so doing draws the flame evenly and thoroughly over every portion of the heating chamber surface. I am thus enabled tomaintain an even heat with one passage. The result of thisconstructiom ii in the kiln with a minimum consumption of fuel which is notonly an economy in fuel but requires less time to fire. Actual test on a number of these kilns which I now have in operation has proven that the same vor a greater amount of ware can be fired in a kiln constructed according to my invention, than can "be fired in the ordinary kiln and with a saving of fifty to sixty per cent. of the amount of coal used in the ordinary kiln.

Although the drawings and above specification disclose the best mode in which I have contemplated embodying my invention I desire :to be not limited to the details of such disclosure, for, in the further practical application of my invention, many changes in form and construction may be made, as circumstances require or experience suggests, without departing from the spirit of the invention, within the scope of the appended claims.

Having fully described my invention what I claim as new and desire to secure by Letters :Patent, is-

1. A kiln of the character described having a heating chamber, a plurality of fire boxes beneath said heating chamber and at one side thereof, a plurality of lateral flues communicating with said fire boxes, a plurality of substantially vertical lines upon one side of said heating chamber and com-municating with said lateral flues anda plurality of substantially vertical flues upon the other side of said heating chamber and connected with said lateral hues and a separate stack for the vertical flues upon each side of said heating chamber.

2. A kiln of the character described, comprising a heating chamber, a plurality of fire boxes disposed beneath said heating chamber andat one side thereof, a plurality of flues communicating with each of said fire boxes and extending laterally beneath said heating chamber, a plurality of lines tending longitudinally beneath said heating chamber and communicating with each of said lateral fines, a substantially vertical flue Copies of this patent may be obtained for of saidlateral fiues,

lateral fines,

one side of the heat ng chamber entering one stack above the top thereof and all of the said vertical fiues on the other heating chamber entering another stack adjacent the said first stack.

3. In a kiln of the character described, a heating chamber, a plurality of fire boxes in a plane beneath the floor of said heating chamber at one side thereof, a plurality of flues communicating with each of said fire boxes and extending laterally beneath the said floor, a plurality of flues extending longitudinally beneath said floor and joining all a vertical flue extending upwardly from either end of each of said all of said vertical fiues entering a stack at the top of said kiln, a partition arranged longitudinally of said stack and separating all of the vertical flues upon one side of the kiln from all of the vertical fiues upon the other side thereof.

l. A kiln of the character described, comprising a heating chamber or inner compartment and an outer shell, a plurality of fire boxes disposed beneath said heating chamber, flues communicating with said fire boxes and extending laterally beneath the floor of said heating chamber, a vertical flue extending upwardly from one end of each of said lateral flues, the said vertical flu-es being intermediate the heating chamber and outer shell, a vertical flue extending upwardly from the other end of each of said lateral fines and intermediate the said heating chamber and outer shell, a stack opening through the top of said outer shell, all of the side of the vertical flues entering said stack and a partifive cents each, thy addressing the Commissioner .of Patents,
